Heterogeneous computing in a strongly-connected CPU-GPU environment: fast multiple time-evolution equation-based modeling accelerated using data-driven approach

Autor: Ichimura, Tsuyoshi, Fujita, Kohei, Hori, Muneo, Maddegedara, Lalith, Wells, Jack, Gray, Alan, Karlin, Ian, Linford, John

We propose a CPU-GPU heterogeneous computing method for solving time-evolution partial differential equation problems many times with guaranteed accuracy, in short time-to-solution and low energy-to-solution. On a single-GH200 node, the proposed meth

The ground structure can substantially influence seismic ground motion underscoring the need to develop a ground structure model with sufficient reliability in terms of ground motion estimation for earthquake damage mitigation. While many methods for

Low-ordered Orthogonal Voxel Finite Element with INT8 Tensor Cores for GPU-based Explicit Elastic Wave Propagation Analysis

Autor: Ichimura, Tsuyoshi, Fujita, Kohei, Hori, Muneo, Lalith, Maddegedara

Publikováno v: ICCS 2024. ICCS 2024. Lecture Notes in Computer Science, vol 14834. Springer, Cham

Faster explicit elastic wavefield simulations are required for large and complex three-dimensional media using a structured finite element method. Such wavefield simulations are suitable for GPUs, which have exhibited improved computational performan
